In the sun and moon and stars. Bp. R. Heber. [Advent.] Appeared in the Christian Observer, Oct. 1811, in 4 stanzas of 4 lines, and headed "2nd Sunday in Advent—Luke xxi." It was repeated with some changes in the text in Heber's posthumous Hymns, &c, 1827, p. 9. This text is that usually followed in the hymnbooks in Great Britain and America.
